pytorch_geometric and gnn
These two tools are competitors, as they are both libraries for building Graph Neural Networks, but each is tied to a different deep learning framework: PyTorch Geometric for PyTorch and TensorFlow GNN for TensorFlow, meaning a user would choose one or the other based on their preferred underlying framework.
About pytorch_geometric
pyg-team/pytorch_geometric
Graph Neural Network Library for PyTorch
Provides a message-passing API for implementing custom GNN layers and pre-built convolution operators (GCNConv, EdgeConv, etc.) that handle node aggregation and feature propagation. Supports heterogeneous graphs, dynamic temporal graphs, and large-scale models with millions of nodes, alongside specialized data loaders for mini-batch training on both small and giant graphs. Includes built-in benchmark datasets and graph transforms for point clouds and 3D meshes, with `torch.compile` and multi-GPU support for production deployments.
About gnn
tensorflow/gnn
TensorFlow GNN is a library to build Graph Neural Networks on the TensorFlow platform.
